How is the TARA effort estimated?

The calculator uses a baseline of 250 manual engineering hours for one moderate-complexity ECU, then adjusts effort based on ECU count, interface count, and current method. It estimates engineering days, not guaranteed project duration.

What does “first structured TARA draft in hours” mean?

It means KAVACH can accelerate the initial structured draft of assets, damage scenarios, threat scenarios, attack paths, risk treatment, and evidence links. Final review, correction, approval, and release remain with the engineering team.

TARA EFFORT ESTIMATOR

Estimate the Effort Behind Manual TARA

The TARA effort calculator estimates engineering person-days for a Threat Analysis and Risk Assessment cycle on a representative ECU. One moderate-complexity ECU is calibrated at approximately 250 manual engineering hours. Adjust ECU count, interfaces, and current method to estimate the effort gap. KAVACH accelerates the first structured draft; final review, correction, approval, and release remain with the engineering team.

This estimate is indicative. Actual effort depends on architecture complexity, item scope, number of interfaces, safety relevance, review depth, tooling, and customer process requirements.

Assumptions

Indicative estimate based on engineering effort for TARA preparation, generation, review, traceability, and report preparation. Actual effort depends on architecture complexity, interface count, available evidence, review depth, and organizational process maturity.

AI generation runtime: approximately 4–5 hours at ~4 tokens/second. Engineering review and validation effort is included in the With KAVACH days above.
